pahahahah seriously when i looked at that picture i was like, man this is a classic joke. how funny is that. anyone have a wire diagram for THIS?!?! theres like 9 miles of wire in there! hope i never have to go into that mess. i bet that weight is killing my 1/4mile time!

when i bought my car, from a private seller, he threw in this big book of wiring. it's got every wire in the car. from head lights to tail lights and shows every thing in between....i think it's called a shop schmatic but that is what you need it is basically a blueprint of the cars wiring and it comes in wicked handy. i'd check evay maybe...i'd scan it and send it to you but the pages r seriously about 14" X 24"

i dont think its as bad as it looks, i would sort it out, try to figure out where the connectors should go (cluster, switches, steering column, a/c), maybe tie the harness back together some, did you get the car like that or did you take the dash out, what parts do you have? i work on mercedes and after you get the carpet out and open the harness on some cars its crazy, figure some benzs have 100 control units that all need to talk to each other, your best bet is to dive in and see whats what and what your working with,
have fun and good luck
